What is a driver?
Driver broadly refers to the hardware that drives a certain type of device.
In the field of computer science, a drive refers to a disk drive. A storage area formatted with a drive letter through a file system. The storage area can be a floppy disk CD、 Hard drives or other types of disks. Click on the corresponding icon in Windows Explorer or My Computer to view the contents of the drive.
To understand the information on floppy disks and CDs, it is necessary to insert them into the floppy disk drive and CD drive respectively, so that the computer can recognize and process the data information on them.
The floppy disk drive and optical disk drive are both located in the chassis, with only their “mouths” exposed, ready to “eat” floppy disks and optical disks at any time.
As for the hard drive, since it is non removable, it is fixed in the drive, which means that the hard drive and hard drive are integrated. When inserting a floppy disk into a floppy disk drive, pay attention to the orientation. For a 3.5-inch disk, the pivot should face downwards and the metal plate should face forward. If you hear the eject button below the drive port pop out with a “click” sound, it means that the floppy disk is inserted properly.
When removing, you should first press the eject button, and the floppy disk will automatically eject a portion. Then, remove the floppy disk. Nowadays, fewer and fewer people use 5.2-inch disks, and 5.2-inch floppy disk drives are rarely installed on computers. It is worth noting that there is a small indicator light above or below the floppy disk drive. When the indicator light is on, it indicates that the computer is reading or writing to the floppy disk in this drive. The indicator light for the hard disk drive is also located on the front panel of the motherboard. When the indicator light is on, it indicates that the computer is reading or writing to the hard disk.
When the drive indicator light is on, do not remove the floppy disk from the corresponding drive or shut it down, otherwise it may cause damage to the disk.
A computer may have more than one software and hard drive, how to distinguish them? We adopt the method of naming the drive. The names of drives are represented by individual English letters, with A and B representing floppy disk drives, C, D, and E representing hard disk drives, and optical disk drives generally represented by the letter H. In this way, we have what we often refer to as “A drive, B drive, C drive, D drive”. Each computer usually only has one optical drive, so it is often abbreviated as “optical drive”.
role
The driver is located in the main control box (Main Controller) throughout the entire control process; Driver –>; Replace the middle section of the motor. His main function is to receive signals from the main control box (NC CARD), process the signals, and then transfer them to the motor and the sensors related to the motor, and feedback the working condition of the motor to the main control box (Main Controller).
Type drive letter
Type of drive A: 5.2-inch floppy disk Volume label: 5.2 floppy disk icon: lost 3.5-inch floppy disk Volume label: 3.5 floppy disk icon: see the first line icon
B Disk Type: 3.5-inch floppy disk Volume Label: 3.5 floppy disk Icon: See the icon on the first line
C drive Z drive type: If there are 5 hard drives, they are CDEFG, the optical drive is H, and the removable disk is I-Z
